I bought this product because I do not like ugly mounting systems and huge that one can see in the majority of cases. The product is discreet when there is nothing placed on it and setting is exceptional and certainly the best of the ones I've tried for 10 years. I use multiple devices (two phones, mp3, ...) and in two different cars since she retired from the air vent in 1 second and replaces the other at the same time. Exceptional product that I plan to buy GPS support release.
